Bone pain in the legs can be a symptom of a variety of conditions, including bone cancer, anemia, infection, injury and overuse, according to MedlinePlus. Osteoporosis, osteomyelitis and leukemia are other possibilities. Bone pain is not as common as joint or muscle pain and should be treated by a medical professional.
Bone pain, swelling and fractures are common indicators of bone cancer, according to Everyday Health. Pain may come and go and get worse during use or at night. As cancer progresses, the pain gets worse and more frequent until it becomes constant. Over-the-counter pain relievers usually do not help ease the pain if cancer is the underlying cause.
Swelling typically occurs in the localized area of pain, particularly if a cancerous mass or lump is near a joint, indicates Everyday Health. Swelling occurs in later stages of cancer progression. Although less common, bone fractures have been known to be caused by a bone tumor that weakens the bone. A fracture can occur during the course of normal activities such as standing up or rolling over in bed. In some cases, patients have felt a surge in the onset of pain in the area prior to the fracture.
Many of the symptoms of bone cancer could be indicative of other conditions such as arthritis or torn ligaments, states Everyday Health. An accurate diagnosis early on helps with successful treatment.
